It's been on before in the last year or so. They're more a series of movies than a series due to the length.
I didn't like his character so only watched one.
Discovered this by accident this morning as it's being screened on a movie channel. Looks like it started on Monday 7th, but there is a Friday repeat.
Jack Taylor is an Irish mystery television drama based on the novels by Ken Bruen.
